When I heard the learn'd astronomer, When the proofs, the figures, were ranged in columns before me,When I was shown the charts, the diagrams, to add, divide, and measure them, When I sitting heard the learned astronomer where he lectured with much applause in the lecture room, How soon unaccountable I became tired and sick, Till rising and gliding out I wander'd off by myself, In the mystical moist night-air, and from time to time, Look'd up in perfect silence at the stars.
